Are you experiencing a frustratingly unresponsive key fob for your 2017 Ford Fusion? The culprit might be a dead battery. Don’t worry, replacing the battery is a simple process that can be done in minutes. This guide will walk you through the steps with clear instructions and helpful tips.

Identifying the Problem: Is It Really the Battery?

Before you start disassembling your key fob, it’s essential to confirm the issue is indeed a dead battery. Here’s how to check:

• Check the key fob’s range: Stand a few feet away from your car and try to unlock or lock it. If the key fob doesn’t respond, it’s likely a battery issue.
• Look for warning signs: Your car’s dashboard might display a warning message indicating a low battery in the key fob.
• Test the buttons: Press the buttons on the key fob. If they feel mushy or unresponsive, the battery might be completely drained.

Gather Your Supplies: What You’ll Need

To replace the key fob battery, you’ll need these supplies:

• A new CR2032 battery: This is the standard battery type used in most Ford Fusion key fobs. You can find them at most convenience stores, hardware stores, or online retailers.
• A small flathead screwdriver or a coin: This will be used to pry open the key fob.
• Optional: A pair of tweezers: These can be helpful for removing the old battery if it’s stuck.

Step-by-Step Guide: Replacing the Battery

Now, let’s get to the heart of the matter. Here’s how to change the key fob battery for your 2017 Ford Fusion:

1. Locate the key fob’s seam: Carefully inspect the key fob for a small seam or gap. This seam will typically be located on the side or back of the key fob.
2. Pry open the key fob: Use your flathead screwdriver or coin to gently pry open the key fob along the seam. Start at one end and work your way towards the other, applying even pressure. Be careful not to apply too much force, as you could damage the key fob.
3. Remove the old battery: Once the key fob is open, you’ll see the old battery. It’s usually held in place by a metal spring. Gently lift the battery out of the key fob.
4. Insert the new battery: Take the new CR2032 battery and align the positive (+) side with the positive terminal inside the key fob. Gently press the battery into place.
5. Close the key fob: Carefully snap the two halves of the key fob back together. Ensure that the edges are aligned correctly.

Troubleshooting Tips: Common Issues

If you’re encountering difficulties while changing the key fob battery, here are some common troubleshooting tips:

• Make sure you’re using the correct battery type: The CR2032 battery is the standard type for Ford Fusion key fobs. Using a different battery type could damage the key fob or prevent it from working correctly.
• Check the battery’s polarity: Ensure that the positive (+) side of the battery is facing the positive terminal inside the key fob. Incorrect polarity can damage the key fob.
• Clean the battery contacts: If the battery contacts are dirty or corroded, clean them with a soft cloth or a cotton swab dipped in rubbing alcohol. This will help ensure a good electrical connection.

Final Steps: Testing and Programming

Once you’ve replaced the battery, it’s important to test it and ensure it’s working correctly.

1. Test the buttons: Press the unlock, lock, and panic buttons on the key fob. If the key fob responds as expected, the battery replacement was successful.
2. Check the key fob‘s range: Stand a few feet away from your car and try to unlock or lock it. If the key fob works within a reasonable range, the battery is functioning correctly.

Important Considerations: Key Fob Programming

In some cases, after replacing the battery, you may need to reprogram the key fob to your car. This is usually necessary if the key fob was completely drained or if you’ve replaced the battery with a new one.

To reprogram your key fob, consult your 2017 Ford Fusion owner‘s manual or visit a local Ford dealership. They can provide detailed instructions on how to reprogram your key fob.

Beyond Battery Replacement: Other Key Fob Issues

While a dead battery is the most common reason for a malfunctioning key fob, other issues can arise. Here are some potential problems and solutions:

• Damaged key fob: If the key fob has been dropped or damaged, the internal circuitry might be affected. In this case, you might need to replace the key fob altogether.
• Software glitches: Occasionally, software glitches can cause problems with the key fob’s functionality. Contacting a Ford dealership or a qualified automotive technician can help diagnose and fix such issues.
• Interference: Strong electromagnetic interference from other devices can sometimes interfere with the key fob’s signal. Try moving away from potential sources of interference (like cell phones, microwaves, or other electronic devices) and see if the key fob works better.
